The KPC-179 Locking Collar is a cast-iron pipe clamp fitting for 48.3 mm OD, 1-1/2" Sch. 40 pipe. It wraps around pipe as a stop ring or removable support collar, using internal hex screws to lock the pipe without welding so structural pipework can be assembled, adjusted, and serviced on site.
Why It Matters
Vertical assemblies often need a fixed stop that can still be moved later. The locking collar gives another connector something to rest on without welding a permanent ring to the pipe.
Key Features
Stop-collar function supports another connector or rotating joint from below.
ASTM A197 cast iron body supports demanding modular pipe structures.
Double-layer hot-dip galvanization helps protect the fitting in indoor and outdoor service.
Internal hex screws secure the pipe without welding, keeping the assembly relocatable.
Applications
Use below fittings in vertical assemblies, as a removable stop, for rotating unfastened pipework, retail frames, guardrails, and modular structures that may need repositioning.
Compatibility
Fits 48.3 mm OD, 1-1/2" Sch. 40 pipe; related sister fittings cover the alternate KUPO pipe clamp diameter.
